AutoGen

AutoGen is an open-source framework for building conversational and autonomous AI agents, enabling rapid prototyping of single- and multi-agent applications. It provides both a web-based no-code UI (AutoGen Studio) and a Python-based developer framework (AgentChat and Core), supporting scalable event-driven, distributed agentic workflows. Extensions allow integration with external tools and Model Context Protocol (MCP) servers, making it suitable for researchers, developers, and businesses aiming to streamline AI workflow automation or experiment with multi-agent systems.
